Primary radar only gives lat and long, it does not give FL, speed or heading. I would be extremely concerned if any pilots thought otherwise. See the report for Egypt Air 990. |
Very Ex BA might be on the money, 4 PAX now suspect, and FBI called in. Still no sign of aircraft.

At where the MAS conference took place, one of the relatives said his brother was one of the passengers on board, and his phone, which has a singapore number, has successfully been dialed.
However till now, the recent two dial has not got any responses. Malaysia authority has recorded this number for further investigation. |
NTSB - Press Release
March 8, 2014 The National Transportation Safety Board has a team of investigators en route to Asia to be ready to assist with the investigation of the March 8 Malaysia Airlines Flight 370 event. The Boeing 777 went missing on a flight from Kuala Lumpur to Beijing. Once the location of the airplane is determined, International Civil Aviation Organization protocols will determine which country will lead the investigation. Because of the lengthy travel time from the United States, the NTSB has sent a team of investigators, accompanied by technical advisers from Boeing and the Federal Aviation Administration, to the area so they will be positioned to offer U.S. assistance. The team departed from the U.S. tonight. The country that leads the investigation will release all information about it. |
If you have enough readings from PSR, you can deduce heading, what i'm saying is SSR gives live, factual readings of heading, received from the transponder, PSR is all guestimation
|
I wouldn't be surprised to find that the two fake passports, on an aircraft travelling to Beijing, is anything really noteworthy.

Stuffed up rapid descent due decompression and forgetting to put on the masks?
|
A single primary radar (skin paint) gives you bearing and distance, nothing else. If you observe multiple returns you can deduce heading and speed.
If you want altitude you need a second radar stations returns time synchronized to the 1st station., and observing multiple sweeps. I'm not counting a tactical radar that has a very narrow beam width and a very narrow scan angle, and has almost no use for civil aviation. BTW: who is the genius that decided mode A would be Code, and mode C would be Altitude? :ooh: |
If you have enough readings from PSR, you can deduce heading, what i'm saying is SSR gives live, factual readings of heading, received from the transponder, PSR is all guestimation Vietnam especially runs round-the-clock military surveillance due to a number of ongoing territorial disputes. |

DME based on PSR is getting VERY oldschool. I'm sure it is still used in accident investigation for confirmation, but with CPDLC and ADS, it's very much a backup |
Stormy Knight, I guess it boils down to this business needs answers, and fairly quickly at that. I imagine most on this blog are either pilots or engineers, all who are using experience as to their opinion what might or might not have happened. For those who suggest it is a poor blog, might take into consideration until something concrete shows up, speculate is all we/us can do. But the very nature of the business puts some urgency into it, and people react to that. Some, suggesting that pilots and engineers iqnore the whole dreadful thing, until something gives them a lead, is nonsense, this affects the whole industry and regardless of whom you work for, most are thinking about Malaysian Airlines right now. No airline, unless totally hopeless, deserves this. And this is considered to be a good airline.

Not really surprised that nothing has yet turned up. Descent from altitude after a catastrophic event, either in large or small pieces, would be subject to trajectories influenced by, amongst others, the forward motion of the aircraft, the force of whatever caused the catastrophy and wind, which could scatter debris over a wide area well away from the point of the event. In effect we are back to basics once the aircraft fails to be a complete unit and the fact is the area to be covered can be thousands of square kilometres.
|
Okay okay I do not work in military and never have or ever will, if you have enough PSR heads in enough different locations then accuracy increases obviously, but in comparison to ADS or SSR? MAH 777's are full CPDLC apparently so that's the most up to date on board telemetry we are going to get before the FDRs are recovered

Can anyone comment on the total lack of ACARS data. The key to being pointed early in the right direction on AF447 was ACARS. With all the resources of PPRUNE members, someone on a positon to know must be in a postion to know if there were ANY ACARS sent.

The South China Morning Post is running pictures of two debris fields spotted from a flight at 36,000ft this morning, they were taken from a MAS flight en-route from PEK to KUL.

A photo taken by a passenger flying the same route has surfaced on twitter: https://twitter.com/JournoDannyAsia/...630848/photo/1. Apparently, it shows an area outside of the search location.

VN Express, Vietnam's largest news site, reports that Vietnam Emergency Rescue Center just announced it has found signal of the missing plane at 9.50am 120 miles South West of Ca Mau cape, the Southern-most point of Vietnam.
The signal is believed to be the ELT (Emergency Locator Transmittor) , which can be activated manually by the flight crew or automatically upon impact. |
No ACARS/ADS means the fuselage broke up immediately, the cockpit was severed from the transmitters
|
glofish Stuffed up rapid descent due decompression and forgetting to put on the masks? I have 2 questions 1. What was the previous rotation of this aircraft? Possibility of package hidden on board and not discovered by cleaners. 2. How long was the aircraft on the ground in semi darkness at KLI? Possibility of of unauthorised entry. |
Platinum: Sky News is reporting no abnormality. I presume that means good data til there was none.
Una: Understood. And I thought your earlier post explained it well, but there was a backlash of but in the XXX investigation... When you think about it, when all else fails the old school stuff still has its place, even if it is in the aftermath of a disaster. It is interesting that they are reporting an increase of the search area in case the aircraft turned back?? |
